Translation Table (SM)
When Translation Bridging is enabled in the AP, each SM keeps a table mapping MAC addresses of
devices attached to the AP to IP addresses, as otherwise the mapping of end-user MAC addresses to IP
addresses is lost. (When Translation Bridging is enabled, an AP modifies all uplink traffic originating
from registered SMs such that the source MAC address of every packet will be changed to that of the
SM which bridged the packet in the uplink direction.)
